-VENT|LAT|N'G RAILWAY CARS AND QARRIAGES.

SPECIFICATION forming part of Letters lF'atent No. 433,942, dated August 12, 1890.

To all whom it may concern:

Be it known that I, SAMUEL HUGHES, of

-- Lin'dsay, in the Province of Ontario, Domini011 of Canada, have invented certain new and useful Improvements in Ventilating Railway-Oars; and I do hereby declare that the following is a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, forming a part hereof.

Myinvention, which willbehereinafterfully set forth and claimed, relates to devices for supplying, purifying, cooling, warming, and extracting air from railway-cars.

The object of my invention is to supply to railway-cars air free from dust and cinders, cool in summer and warm in winter, and to extract the vitiated air, and to effect the change without causing drafts.

Figure 1 is a sectional elevation of a car having my improvements applied. Fig. 2 is a portion of Fig. 1 on a larger scale. Fig. 3 is a horizontal section on line 00 01:, Figs. 1 and 2. Fig. 4 shows a modification of the connection between the air-tube and the float, and Fig. 5 shows a modification of the heating arrangement.

In a convenient corner or other part of a car B, Fig. 1, I place a tank A, adapted to be partly filled with water w. Some distance above the highest intended water-level in said tank is fitted a grate or ice-rack 13, which carries an upwardly-proj ecting tube 1), around which iceI may be placed.

0 is a fresh-air tube passing through the roof of the car and terminating above the roof in a trumpet-mouthed twin funnel c 0, one month facing forward and one rearward. At the point where the trunk of the tube branches out into twin shape a flap-valve c may be fitted, adapted to close either one or other of the two throats. The trunk of the tube O passes through the tubular space formed by the tube 1), and is prolonged downwardly either telescopically by an overlapping lower end O and a soft-packing ring 0 as in Figs. 1 and 2, or by flexible branches 0, as in Fig. 4. The lower end '0 of said tube is adjustably supported upon an axle or cross-bar D, journaled upon a float D, which may be tubular, as shown in Figs. 2 and 3, or may be constructed of cork or other like niaterial having the required floating power.

The mouth of said tube 0 or C is covered with a perforated plate 0', having alarge perforation in the center. An adjustable damper 0 is inserted in the pipe 0, to regulate the flow of air, Said float carries, at a little distance above the surface of the water, a perforated plate or false bottom E, upon which may be placed Florida moss, horsehair, shavings, or other loose light material E, to check the splashing of the water. The water-space may be filled with steam, hot water, or hot-air-heating coils F, for heating the water; and similar heating-coils F may also be placed in the upper part of the tank above the ice-chamber, as shown in Fig. 2, or in a separate chamber A, connected with the tank A, as shown in Fig 5. The heating-space containing the coils F communicates freely with the ice-space, and from said heating-space the air is discharged into the body of the car by a tube a. The tank is also fitted with water-gage G and draw-off cock H.

The device operates as follows: In warm weather ice I is placed on the ice-rack B and water w is placed in the bottom of the tank. When the car is in motion a current enters that one of the months 0 which faces forward and passes down the tube 0 through the strainer 0" upon the surface of the water w. The heavier impurities of the air are retained bythe water and the air passes upward through the false bottom E, the filtering material E, and through the ice I, where it is cooled and discharged into the car by the pipe (1.. In cold weather ice is not used, but the water w and the chamber A may be heated by means of the coils F and F. As the float rises and falls with the surface of the water w the distance between said surface and the strainer c" in the discharge-mouth of the air-tube is always kept uniform; but said pipe may be set higher or lower in its support D at pleasure.

To remove the vitiated air from the body of the car, I use the following arrangement: I perforate the door or partition K, separating the water-closet K, by louvers k or the like, and in said space I place another air-pipe O c 0, similar in all respects to the one described above. The lower end of said tube is branched out at 0 and one branch connected with the soil-pipe m of the closet M and one with the soil-pipe a of the urinal N.

Thus the pressure of air upon the mouth 0, caused by the forward motion of the car, will force a current down the pipe 0 and through the soil-pipes m and n, thereby causing slight vacuums in the closet-bowl and urinal M and N, respectively, which Will thus draw and exhaust the air from the space K, whichin turn will be filled from the body of the car through the openings k.

I claim as my invention- 1. In a ventilating system for railway-cars, the combination of a tank A, havinga Waterspace, air-space, and ice-space, and provided with water-gage and draw-01f cook, the ice- V the combination of a tank partly filledwith water, a float upon the Water supportinga false perforated floor above the Water-level, and

the lower end of an air-pipe, an air-pipe terminating above the car-roof in a trumpetmouthed twin funnel, an adjustable pipe-connection between the float and said pipe, an

ice-rack above the false floor and having a tubular space to allow the air to pass through the ice-space, coils for heating the water and the air, a discharge-pipe for discharging the air from the tank into the body .of the car, perforations in the partition separating the body of the car from the closet-space, an airpipe in said closet-space similar to the airpipe hereinbefore referred to, but having its lower end branched out and connected withthe soil-pipes of the closet and urinal, and the soil-pipes so connected, substantially as set forth.

3. In a ventilating system for railway-cars, the combination of the tank A, float D, an air-pipe C, having its upper end terminating in a trumpet-mouthed twin funnel cc, an adjustable pipe-connection between said pipe and the float, and the perforated false floor E, supported above the top of the float, substantially as set forth.
